慶州蘿井の八角形建物址における柱配置計画に関する研究

摘要

本稿では慶州蘿井の八角形建物址を対象にして柱配置の形態とその決定過程、そして柱配置の決定に影響を与えた要因を中心にして考察を試みた。この結果をまとめると次のようになる。1)第3期に築造された八角形建物は単層構造として、その平面には井字回転形の非常に特殊な柱配置の形式が適用された可能性が高い。%This study is about the octagonal building of GYEONGJU NAJONG, the remains of a ritual facility of ancient Shilla Dynasty. The purpose of this study is to examine the column arrangement of the octagonal building, and reveal the determinant factors for column arrangement by reviewing the sequential processes in building the facility. The results are as follows ： the octagonal building was designed with special structure that internal structure is rotated against external column arrangement. Difference in the number of columns between inside and outside was caused by restrictions on the scale of the inner and outer circumference. And it induced rotation of the internal structure for the external column array. The circumference of internal and external column of the octagonal building was defined to include the core portion of predecessor facility, consisting of the central pit and the six pits.
